Hexamethylenetetramine .01 part. Benzoate of lithium or sodium .3 parts.Lanolin in alcoholic solution approximately 3 parts. I

In preparing the cosmetic, one part of agar or Bengal isinglass is mixedwith from 300 to 500 parts of a one percent solution of boric acid andheat is applied and the solution placed under a pressure ofapproximately two atmospheres.

and after this solutionhas been prepared,

there is added thereto a solution of gloiopeltis furcata of a strengthof and the solution obtained is capab ver thin and soft film on the skinof the .15 parts in ten parts of water and a mixture: of .01 part ofhexameth lenetetramine and .3 parts of "benzoate of lithium or sodium,together with This ,is done to reduce coagulation of the Bengalisinglass,
